Jan Hus

Jan Hus (; ; 1370 – 6 July 1415), sometimes anglicized as John Hus or John Huss, and referred to in historical texts as ''Iohannes Hus'' or ''Johannes Huss'', was a Czech theologian and philosopher who became a Church reformer and the inspiration of Hussitism, a key predecessor to Protestantism, and a seminal figure in the Bohemian Reformation. Hus is considered to be the first Church reformer, even though some designate the theorist John Wycliffe.}} His teachings had a strong influence, most immediately in the approval of a reformed Bohemian religious denomination and, over a century later, on Martin Luther.

After being ordained as a Catholic priest, Hus began to preach in Prague. He opposed many aspects of the Catholic Church in Bohemia, such as its views on ecclesiology, simony, the Eucharist, and other theological topics. Hus was a master, dean and rector at the Charles University in Prague between 1409 and 1410.

Alexander V issued a Papal bull that excommunicated Hus; however, it was not enforced, and Hus continued to preach. Hus then spoke out against Alexander V's successor, Antipope John XXIII, for his selling of indulgences. Hus' excommunication was then enforced, and he spent the next two years living in exile.

When the Council of Constance assembled, Hus was asked to be there and present his views on the dissension within the Church. When he arrived, with a promise of safe-conduct, he was arrested and put in prison. He was eventually taken in front of the council and asked to recant his views. He refused. On 6 July 1415, he was burned at the stake for "heresy" against the teachings of the Catholic Church.

After Hus was executed, the followers of his religious teachings (known as Hussites) refused to elect another Catholic monarch and defeated five consecutive papal crusades between 1420 and 1431 in what became known as the Hussite Wars. Both the Bohemian and the Moravian populations remained majority Hussite until the 1620s, when a Protestant defeat in the Battle of the White Mountain resulted in the Lands of the Bohemian Crown coming under Habsburg dominion for the next 300 years and being subject to immediate and forced conversion to Catholicism in an intense campaign.
